Body iron can be present as either the highly toxic Fe2+-ions or as harmless, insoluble Fe3+-ions. Ferritin detoxifies Fe2+-ions by converting them to the insoluble Fe3+- www.intechopen.com
WebFerritin is a protein that stores and releases iron to prevent diseases associated with iron dysregulation in plants, animals, and bacteria. The conversion between iron-loaded holo-ferritin and empty apo-ferritin is an important process for iron regulation. To date, studies of ferritin have used either ensemble measurements to quantify the characteristics of a … WebBackground Ascorbic acid (vitamin C) enhances iron uptake in human intestinal cells. It is commonly believed that the enhancement is due to the capacity of ascorbic acid to reduce ferric iron to ferrous iron. Other suggestions have recently been made about the effects of ascorbic acid on the cellular metabolism of iron. These effects must be investigated for …
WebApr 12, 2024 · The second gene encodes the protein ferritin, which functions as a storage depot for up to four thousand iron atoms per protein molecule in both plants and humans. Since the ferritin gene is under the control of an endosperm-specific promoter, ferritin comprises a sink for iron in the center of the endosperm. WebMay 15, 2002 · Increasingly, perturbations in cellular iron and ferritin are emerging as an important element in the pathogenesis of disease. These changes in ferritin are …
WebFerritin and iron storage. Ferritin is composed of 24 subunits, heavy (H) and light (L), with varied ratios of H to L in different cell types and physiologic conditions. Ferritin H has ferroxidase activity to convert Fe 2+ to Fe 3+ inside ferritin shell. Iron is imported and exported through the channels constructed by ferritin H or L subunits.
